hash: fix memory allocation of cuckoo key table
hash: fix memory allocation of cuckoo key table

When calculating the size for the table which allocates
the keys, size was calculated wrongly from multiplying
two 32-bit variables, resulting on a 32-bit number,
before casting to 64-bit, so maximum size was 4G.
